To all whom it may concern.-

Be it known that I, RoBERTAsBURY Rnensand exact description thereof, reference be.

e ing had to the accompanying drawings, in 10 which Figure 1. is a front elevation of a machine embodying my-invention; Fig. 2, a top plan view of the protector shaping and support ing mechanism, the construction being such as is adapted for applying protectors to shoe-soles; Fig. 3, a like view with the sha ing mechanism opened; Fig. 4, a longitu inal section on the line 4 4 of Fi 3 Fig. 5, a cross-section on the line 5 5 of Fig. 3; and

Fig. 6, a top plan view, similar to Fig. 2, showing the invention embodied for applying protectors to shoe-heels.

The object of my' invention is torender easy to the operator the doing of the work and to increase the speed of machines for inserting protectors in the heels and soles of shoes; and to this end my invention consists in the machine for applying protectors constructed substantially as hereinafter specified and claimed.

The type of protector for operation upon which my machine has been especially designed is one that consists of a transverselycorrugated or sinuous metal strip from which As applied to the eels, and usually to the soles, of shoes, the protector is given a curved form corresponding substantially to the outline or contour of the heel or sole, as the case may be, and in 4 -machines heretofore used for inserting such protectors it has been necessary to bend the corrugated or sinuous strip by hand to the desired shape before placing it in the driving or inserting machine. As will be evident,

such a procedure is both slow and uncomfortable to the operator, for by reason of its form the hands are apt to be scratched or cut in the work of bending the strip into sired curved form without the tedious and uncomfortable hand manipulation which has heretofore been employed.

In respect of the protector-inserting mechanism the machine which I have selected to illustrate an embodiment of my invention is similar to the machine forming the subject of United States Patent N 0. 696,289, dated March 25, 1902, which comprises a stationary support for the protector corresponding in form thereto, a yielding table for the heel lift or tap into which the protector is to be inserted, and a ram for applying pressure to the heel lift or tap to cause the entrance therein of the protector.

In the machine illustrated in the drawings there is a frame or standard A, having a shelf or bracket a, upon which is mounted a plate B. Resting upon and supported by the latter are one or more rib-form pieces or bars, which form the supports for the protectors to effect their insertion into the shoe part, one. only being employed where a single protector is to be drivenas, for instance, in case of a heel-liftand several being employed for simultaneously driving a number of protectors, as in the case of shoe soles or taps. The protectors having a curved form, the bars C are likewise curved.

Supported above the plate B yieldingly or movably by a proper number of coiled springs D is a table that receives and supports the 5 shoe part into which the protectors are to be inserted, said table having a slot for the accommodation of each protector-supporting bar C. Said table comprises a plate E, having upon its up er side a curb or wall 6, hav- 9o ing a contour ike the contour of the outer side of the outermost protector-supporting bar C, where several are employed, as illus trated in Figs. 2 to 4, and one or more sliding members, (according to the number of pro- 5 tectors to be inserted,) each in the form of a plate, such sliding members being slidably connected to the plate E in any desired waysuch as, for example,by dovetail bars or g1b s f and grooves e in the plate. The machine as illustrated in Figs. 2 to 4. is for driving two curved protectors simultaneously, and therefore there are two sliding sections F and G, one of which, F, has an. outer edge that corresponds in form to the inner edge of the outermost protector-supporting bar C and an inner edge that corresponds to the outer edge of the innermost protector-supporting bar 0, while the second sliding section, G, has an outer edge that corresponds to the inner edge of the innermost protector-supporting bar 0. Attached to the last-named movable section is a handle H, by which such sec- .tion may be moved, and pins g, projecting downward from the other sliding section, and

slots 9 in the gibs of the section to which the handle is attached, into which slots said pins 9 project, constitute means whereby movement from the section having the handle may be imparted to the other section.

The purpose of the construction of table .just described is to enable the placing in the machine of the straight transversely-corrugated or sinuous protector-strips and their bending into the desired curved shape. One of the sliding sections being withdrawn wholly from within the curb or wall 6 and the other sliding section being wholly withdrawn from the other sliding section, as illustrated in Fig. 3, a straight strip is laid upon the table in front of each sliding section, straight edges or surfaces (3 on the table formlng guides or ga es therefor to fix their positions sidewise an lips or projections e on the plate E engaging their ends to fix their positions longitudinally. The handle H being .taken hold of and the sliding section G, to which it is attached, being moved toward the other sliding section, the portion of the proteeter-strip between the two sections will be .forced by one slidin section into the other, and the second sli ing section being also moved by reason of the pressure to which it is subjected through the interposed strip it will engage the second strip and force it into the space surrounded by the curb or wall 0. The two sliding sections being moved as far as they can be, the two strips will be bentto a conformation corresponding with the respective curved bars C, and they will beplaced in position over the same. The strips being thus bent to the required shape and placed in position for driving, the driving operation is effected by the descent of a ram or plunger I, which is connected by a pitman J with a crank-shaft K, mounted in bearings on the top of the frame or standard A and suitably revolved by power. To prevent the accidental displacement longitudinally of the strips when they are engaged by the ends of the sliding sections, such ends are roughened,

as by being provided with small teeth. To withdraw the sliding sections, the handle H is caught hold of and pulled outward, resulting in drawing outward the section to which it is attached and through the slot-and-pin connection with the other section drawing the latter outward.

The base-plate B, upon which the table is mounted, is movable in order to enable the table to be moved from position beneath the ram or plunger I for more convenient access to the table and back again, and for this purpose such plate is pivoted atone end to a stud or post L on the bracket or shelf a, and it is provided with a handle I), by which it may be conveniently manipulated. A spring M, coiled about the stud or post L, beneath the bracket or shelf a and having one end fastened to the latter and the other fastened to a collar Z on the stud or post L, acts to normally swing the plate to a position from beneath the ram or plunger, so that after the rotectors have been inserted the operator has merely to let go the handle I), whereupon the table is automatically moved from position beneath the ram or plunger. The machine operates with such rapidity that the presence of the work beneath the plunger is required for but a very short time, and this makes it unobjectionable for the operator to hold on to the handle to kee the table with the work upon it in position for actioif of the ram or plunger. A stop bar or pin. 6, attached to and projecting from the plate B, is provided to fix the position of the parts when the plate is swung to place the work in position for the action of the ram or plunger.

As shown in Fig. 6, the machine is adapted for forming and driving but a single protector at a time, as in the case of protectors for heels, in which case, as is illustrated, but a single sliding section G is required.

As shown in Fig. 3, if it be desired to drive a straight or uncurved protector this can be done by roviding a straight slot g in the outer sliding section G or the one to which the handle H is applied, in which the strip is placed before said section is moved into position for the operation of the machine and providing a straight supporting-bar C.

Although I have shown and described with some particularity the details of construction of a machine embodying my invention and as designed for operating on a protector of a particular construction, it is to be understood that the invention may be embodied in machines differing in construction from what is shown and for operating upon protectors of other form.

Having thus described my invention,wl1at I claim is 1. In a driving mechanism, the combination of a bent support for the thing to be driven, a curb or w. 1 adjacent the support, and cormeans for giving to the thing to be driven a form similar to said support by pressing it against said wall orcurb.

2. The combination ,of driving mechanism, comprising a movable support for the object to receive the driven thing, a stationary support for the thing to be driven, and means for giving to the thing to be driven a shape corresponding to the support therefor.

3. The combination of driving mechanism, comprising a ram, a movablesu port for the object to receive the driven t hing, and a stationary support for the thing to be driven, and means for giving to the thing to be driven a shape corresponding to the support therefor.

4. The combination of a driver comprising in part a rest or support, a curb or wall contiguous thereto, and a plate movable toward said curb or wall to conform thereto the thing to be driven, and simultaneously placing it in position to be acted upon by the driving mechanism.

5. The combination of a drivingmechanism, comprising a curved stationary support for the thing to be-driven, and means for giving to the thing to be driven a form corresponding to that of said support, and placing it upon the latter.

6. The combination of a driving mechanism, and means for shaping and positioning an article to be driven comprising a plate having a curb or Wall corresponding to the contour to be given an article, and a second contour to be given an article, a second movable plate having inner and outer surfaces corresponding to articles to be shaped, and a third movable plate shaped in correspondence with the inner surface of the second plate.

9. The combination of a stationary plate having a curb or wall corresponding to the contour to be given an article, a second movable plate having inner and outer surfaces corresponding to articles to be shaped, a third movable plate shaped in correspondence with the inner surface of the second late, and means for transmitting movement rom one movable plate to the other.

In testimony that I claim the foregoing I have hereunto set my hand.
